.7 Be it known that I, WILLIAM H. ALLlVIAN,

a citizen of the United States,residing at Blythedale, iii the county of Harrison and State of Missouri, have invented new and useful Improvements in Flying-Machines, of which the following is a specification.

, This invention comprehends enerally i1n-' provements in that class 0 inventions known as aeronautics and more Particularly relates to flying machines.

It is the principal aim and object of the present invention to provide a device of the abovev mentioned character wherein a pr peller of novel construction is employed for engaging the air to assure of the lifting of the deviceupwardly permitting of the op- =erator to maintain the machine in vertically stationary position so that bombs or the like may be accurately dropped on objects either in thew ater or onthe surface of the land.

It is an equally important object of this invention to provide a device ,of thefabove mentioned character wherein-auxiliary propellmg means is employed for directing the device horizontally through the atmosphere while operating in conjunction therewith is guiding means for permitting of the operator to properly steer the machine or device. More particularly this invention contem- -'plates the provision of a' device-of the above mentioned character wherein the improved main propellers desirably embody spaced disks composed of semi-circular con caved sections disposed -at an angle relative to each other toinsure of the proper engagement with the air so as to readily lift the device.

- Among the other aims and objects of this 40 to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forminga part hereof, and wherein is disfclosed for the' purpose of illustration a con- :venient and satisfactory embodiment-of the invention. It is to be noted in-this cons FLYING-MACHINE.

nection that minor changes in the construction and arrangement of parts may be made without departingfrom the'principle of operation' f the various parts.

The invention .is clearlyillustrated in the accompanying drawings, in which:

Figure 1 is a sideelevation of the improved device.

I Fig. 2' is, a front elevation thereof. -Fig. 3 is a top plan view of the device, a d

' 2'and side rails 3. Secured to the upper surface of the base is .a box 4 from which-projects a vertical sleeve or post 5 while journaled in the base through the box and sleeve Fig. 4 is a horizontal section taken on line r and projecting above the sleeve is a vertical As intimated, an improved main propellingmeans isemployed in the" resent 'instance consisting of superpose disk-like propellers 7 andJ'S rigidly connected tolthe upper portion of the shaft 6, Each propeller in the present instance is composed of semi-circular concaved sections 9-secured in opposed relation with res ct to each other on opposite sides of the s aft and disposed I at an angle" relative to each other to assure of the proper engagement with the atmosphere during rotation whereby'to effectively lift the machine upwardly. In this connection it is to be observed that the sections 9 of the propeller'fl are disposed at right angles with respect to-the sections 9 of'the lower propeller 8, the arrangement being.

clearly illustrated in the drawings In order to actuate the shaft and consequently the propellers an engine 10 of a suitable type is mounted on the base 2 andis connected with a crank shaft 11 journaled on a sup-v port 12 and in the post 4:. A-bevel pinion-13 is mounted on one end of the shaft Hand is disposed in the box 4 so as to mesh wlth the bevel gear 14 carried by the lower: end of rigidly connected to the post 5 so as to similar in construction to the project at right angles therefrom and is braced with respect to the latter by means of braces 16 while journaled in bearings 17 iii this sleeve is a horizontally disposed shaft 18 the outer end of which carries the aux- 'iliary' propeller 19 composed of sections 20 sections 9 though of a smaller size. In rotating the auxiliary propeller 19 a vertical'shaft 21 is rotatably mounted in the base 2 and in a support 22 the upper end thereof bearing the bevel gear 23 which meshes with the bevel gear or pinion 25! on the shaft 18. A hearing 25 is operative-1y connected to the top of the shaft 21 and has j ournaled therein the outer end of the shaft 18 and through the medium of this bearing the shafts 18 and 21 are at all times properly supported relative to e aoh. other.

Eor the purpose of transmitting rotary motion to the shaft 21 a bevel gear26is carried by the shaft 21 and meshes with another bevel gear 27 loose on the outer end of the shaft 11. This gear 27 is formed with a stationary clutch base 28 with which operates a' movable clutch member 29 slida l but non-rotatablv connected to the shaft 11. A manually operable swi'ngingly 'mounted lever 30 is operably connected to the support 22 and has the lower forked end 31 disposed in an annular groove 32 in the movable clutch member 29. It is apparent that by shifting this lever motion may be transmitted to the shaft 21 from the shaft 11 or else. the shaft 21 may be left idle, as is apparent.

In orderto' uide or steer the device a rudder 33 is swmgingly connected for horizontal movement between spaced laterally disposed brackets which. project from the post 5 by means of a spindle 35. An arm 36 continues from the inner end of the 'rudder and is operably connected with the slot tedend 37 of theimanually operable and sw'ingable lever 38 on the lower bracket arm second mentioned shaft and the last mennecessaryv to swing the. levert-o either side.

It is believed in view of the foregoing description that a further detailed description of the operation of thednvention is entirely unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent:

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from .the scope thereof it is intended that all matprising a carrier, a boX thereon, a post ris-i V 111g from the box, a vertical shaft ournaled through the post and the box and projecting above the post, a pair of supereposed lifting and sustaining propellers connected to. the

projecting end of the shaft, a prime mover on thecarrIer, a shaft rotatable by the prime mover transmission means connected to the shafts and positioned in the box which insure of the rotation of the main propellers at all times, a sleeve projecting from the post, a horizontal shaft journalcd in the sleeve, an auxiliary propeller connected to the outer end of the horizontal shaft, another vertically disposed shaft journaled in the carrier, means for transmitting motion between the last mentioned vertical shaft and the hof'izontal shaft, transmission means between the second mentioned shaft and the last mentioned vertical shaft, manually operable clutch means for controlling the transmission of movement between the tioned shaft, and manually operable steer-' ing meansconnected to the 0st.

In testimony whereof I a iX my signature.

WILLIAM H. ALLMAN.
